  • What are Beamsplitters?

    Non-polarizing beamsplitters split light into a specific R/T ratio while maintaining the incident light's original polarization state. For example, in the case of a 50/50 non-polarizing beamsplitter, the transmitted P and S polarization states and the reflected P and S polarization states are split at the design ratio.
